Problems solved by technology

[0002] When watering flowers or washing the car, it is generally necessary to connect the water pipe to the hose and lead the water to the place where it is needed, but when these hoses are used, storage becomes a problem
Users generally put the portable hose in the trunk of the car, or roll it up and throw it on the balcony or yard, which causes the hose to become knotted; thickening the wall of the portable hose can alleviate the knotting phenomenon, But it also makes the hose bulky and unwieldy

Embodiment 1

[0030] This embodiment provides a telescopic water pipe, which includes a pipe body, a pipe joint and a valve joint.

[0031] The tube body includes an inner tube and an outer tube, the inner tube is located inside the outer tube, and the inner tube is made of an elastic material that can be stretched to 2-6 times its original length in an uncompressed or unstretched state, such as natural Rubber, etc.; the outer tube is made of non-elastic fabric, such as knitted or braided nylon, polyester, or polypropylene material, and the length of the outer tube is longer than that of the inner tube.

[0032] After connecting the water source, a higher water pressure will be formed, and the inner pipe will expand when it enters the water. The outer pipe will limit the deformation of the inner pipe and protect it to a certain extent. Therefore, the outer pipe must not only be light, flexible, bendable, and indestructible Expansion requirements, but also have sufficiently strong characteri...

Abstract

The invention discloses a telescopic water pipe. The telescopic water pipe includes a pipe body, a pipe joint and a valve joint; the pipe body comprises an inner pipe and an outer pipe, the inner pipeis located inside the outer pipe, the inner pipe is made of an elastic material, the outer pipe is made of a fabric without elasticity, and the length of the outer pipe is greater than the length ofthe inner pipe; and one end of the pipe body is provided with the pipe joint, and the other end is provided with the valve joint. The telescopic water pipe of the invention is fixed on parts such as afaucet through the pipe joint to make high-pressure tap water flow into the inner pipe, and when a valve is closed, the inner pipe is deformed and elongated due to the pressure of tap water, the diameter of the deformed inner pipe is limited by the outer pipe, thereby achieving elongation of the telescopic water pipe; and when usage of the telescopic water pipe is completed, the inner pipe shrinks due to disappearance of the pressure inside the inner pipe, which drives the outer pipe to be contracted together to achieve withdrawal of the telescopic water pipe, and the telescopic water pipe isconvenient for usage and storage.

Description

technical field [0001] The invention relates to a watering hose, in particular to a telescopic water hose. Background technique [0002] When watering flowers or washing cars, it is generally necessary to connect the water pipe to the hose and lead the water to where it is needed, but when these hoses are used, storage becomes a problem. Users generally put the portable hose in the trunk of the car, or roll it up and throw it on the balcony or yard, which causes the hose to become knotted; thickening the wall of the portable hose can alleviate the knotting phenomenon. But it also makes the hose bulky and inconvenient to use. Contents of the invention [0003] The object of the present invention is to provide a telescopic water pipe, which can be extended during use and can be shortened after use, which is convenient for storage. [0004] The present invention adopts the following technical solutions to solve the technical problems: a telescopic water pipe, which includes...
